First the service name can be taken from the class['Myslq'] so this has
to be adjusted as well to take the mysql-bootstrap into consideration.
Second, is a improvement. The pc.bootstrap=1 isn't required so the
configuration is the same on all the nodes.
Third I increase the default boot time of the galera because of the
synchronization that can take some time.
This must be applied with the code associated to GH-126 to work
properly.
Both should close GH-11
